Improvement in sulky-plows



MILO A. ELLIOTT, OF STRATFORD HOLLOW, NEW HAMPSHIRE.

`l MPROVEM ENT IN SULKY-PLOWS.

Specification forming part of Letters Patent No. 112,434, dated March 7,1871.

To all whom 'it may concern:

Be it known that 1, MILo A. ELLIOTT, of Stratford Hollow, in the countyof Coos and State of New Hampshire, have invented anew and usefulImprovement in Sulky-Plows 5 and I do hereby declare that the followingis a full,

i clear, and exact description thereof, which will enable others skilledin the art to make and i use the same, reference being had to theaccompanyin g drawing, forming part of this specifi cation.

Figure 1 is a side view of my improved plow. Fig. .2 is a top view ofthe'same.

Similar letters of reference indicate corresponding parts.

The 'object of my invention is to improve upon means hitherto employedby the public s l. to adjust the plow, to steadyts movement,

and to prevent the furrow-slice from falling 1 back into the furrow.

I will rst describe my invention in connection with all that isnecessary to a full understanding thereof, and then clearly point it outin the claims.

A is the tongue, to the rear part of which the double-tree B is pivoted,and the lrear end of which is hinged or jointed to the forward end ofthe bar O, which is the side bar of the frame. D is the other side bar,which is coni if nected with the bar C at its forward end `by thecross-bar E, and at its rear end bythel `cross-bar F.

G is the plow, the upper end of the standard H of which is` securelypivoted to supports attached to or formed upon the side bar C, so

that the said `plow. may have a free lateral movement upon itspivoting-points.

Iis a lever, which is pivoted to the plowstandard H in such a way thatit may be moved forward and back upon its pivoting-points,

but will carry the plow Gr H with it whenv moved laterally.

The lever I, when moved back into the poy y sition shown in Figs. 1 and2, enters a notch or slot in a projecting part or arm of the frame,

and holds the plow rigidly in a vertical posii tion.

i J is an arm or horn, attached to the rear cross-bar, F, in such aposition that it may prox ject inthe rear of the plow Gr, to prevent thesod raised by said plow from dropping back into the furrow. The arm Jshould be adj ustably attached to K are the wheels, which are placed andpivoted in slots in the rear parts of the bars L.

The wheels K and bars L are placed in lougitudinal slots in the sidebars C D, and the forward ends of the said slotted bars L are pivoted tothe bars O D in the forward parts of the slots of the said bars O D.

To the rear ends of the slotted pivoted bars L are pivoted the lowerends of the short connecting-bars M, the upper ends of which are pivotedto the levers N. The rear ends of the levers N are pivoted to the rearparts of the side bars G.D or to the rear cross-bar, F.

The forward ends of the levers N extend forward into such a positionthat they may be reached and operated by the driver from his seat, andare connected with the forward ends of the side bars C D or with thefront crossbars, E, by ropes or chains O.

To the front cross-bar, E, is attached an arm, P, which projectsdownward and curves rearward, as shown in Fig. 1, and is designed tosteady and balance the machine.

Q is the drivers seat, the standard of which is attached to the frontcross-bar, E, of the frame.

\ By this construction, by raising the lever I into a vertical positionit may be moved to the right or left, to cause the plow to cut a ywideror narrower furrow; and by turning the lever I down in front into ahorizontal position, Vthe plow G may be turned above the frame of themachine, for convenience in moving from place to place.

By operating the righthand lever N, the` right-hand wheel K may beraised and lowered to regulate the depth of the furrow; and by operatingthe left-hand lever N the left-hand wheel K may be raised and lowered toadjust the plow for working upon a side hill. Y

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. The arm J, projecting laterally beyond the plow,and following in the rear thereof, for the purpose of preventing the sodfalling back into the furrow.

2. The application of the downwardly-projecting and rearwardly-curvedarm P to the cross-bar E of a plow-frame, for the purpose of balancingthe machine and enabling the plow to run with uniform steadiness.
